My parents bought me a binoviewer for my NexStar 8SE and I need to get one/some eyepieces to go with it. I currently have decent quality Celestron 25mm, 15mm, and 6mm eyepieces and a barlow lens (the lens that comes with it plus their accessory kit).

I'm considering buying one additional 25mm, giving me two decent ranges to use due to the barlow lens. Is this a good idea, or would I be better off buying two zoom lenses?
